Who Will Be Singing at the Wedding?
Attending this event would be challenging, to put it mildly. There are likely to be a lot of people there. Putting a damper on the festivities by getting interrupted while you’re belting out the classics at a wedding reception is like throwing cold water on the celebration. It was the job of the bandleader to get everyone in the spirit of things, but you can’t hog all the spotlight for yourself! That may be the sole purpose of a song under some circumstances.
To be honest, I don’t think that’s what you have in mind at all. Were the guests at the wedding in need of this particular form of entertainment? Who warned them that it wouldn’t go down well if they did it in the first place?
